4. Seminar - Assignment of the first semestral project

The first semester project - deadline for submission is week 10

Complete assignment of the first semester project: 01_semester_project.pdf

Project evaluation:

Transcription of the simulated program into the symbolic address language 2
Rewrite of the program in a machine code with an example of coding of at least two instructions 1
Design of system (CPU, memory, program) in Verilog language 6
Simulation (verifying the functionality of the design) 4
Sources formating, commentaries of solution and design functions and description of system functionality, schematic 2
Total: 15

It is necessary to achieve at least 6 points (inclusive) for the successful submission of the project.

The use of C language compiler mips-elf-gcc is allowed, same as the program mips-elf-as for translation from symbolic address language to machine code and for relocation and completion of binary code linker mips-elf-ld can be used.

The Debian packages can be download from binutils-mips-elf_2.20.51-1_amd64.deb and gcc-mips-elf_4.4.4-1_amd64.deb

Next commands can be used for installation

sudo dpkg -i Downloads/binutils-mips-elf_2.20.51-1_amd64.deb
sudo dpkg -i Downloads/gcc-mips-elf_4.4.4-1_amd64.deb

You can base your data and program memory modules on the following Verilog code fragment - take it as an inspiration which is sufficient for our purposes.:

module dmem (input clk, we,
             input [31:0] a, wd,
             output [31:0] rd);
  reg [31:0] RAM[127:0];
  assign rd = RAM[a[7:2]]; // word aligned
  always@(posedge clk)
    if(we) RAM[a[31:2]] <= wd;

module imem (input [5:0] a,
             output [31:0] rd);
  // The "a" is the address of instruction to fetch, what
  // for our purpose can be taken from ProgramCounter[7:2]
  reg [31:0] RAM[127:0];
  initial  $readmemh ("memfile.dat",RAM);
  assign rd <= RAM[a]; // word aligned
